Technical note: this PDF only contains volume 1 (of 4)
Technical notes only--as of 20 June 2009:
Unless I have misunderstood the intent behind the Google item notes (and the similar archive.org note) for this scan, the claim is that this PDF contains all 4 volumes in one file ("Item notes: v. 1-4 - 1918"). In fact the PDF ends on p. 282 of the scanned book, so that this appears to only contain volume 1 of 4, the last volume of which continues more than 1327 pages.
Also: page 56 of the book (= p. 64 of the PDF) is illegible.
Addendum (26 Feb 2010):
The publisher, presently listed as Plotonist Press, is actually Platonist Press
